I have a hard time believing this guy since I won't think any provider (unless extremely newbie friendly) that would see a guy w/o verification especially if he joined that close (if not after) his review.
Because he was/is a newbie, I'm more likely to believe Kia on this one. Although I don't know her, I would think a provider would be kind of dumb to do what he said in ROS. But stranger things have happened, but generally not with a well reviewed provider. I cann't go into it further w/o revealing ROS.
I don't know if Kia is "deserving" of a ban because someone told her about the ROS of the review. Cut and paste and sending it to her is a whole lot different than paraphrasing it. Plus the non private comments on the review are enough to wonder WTF did this guy say or do to warrent so many guys saying he was wrong. Also, a fair number of clues were given to the ROS contents. Any good provider is going to recoil from a negative review, especially if she believes it to be false.
Ban (or put in timeout) the dude already and lets move on. Its doubtful either party will give a retraction. Gove Kia a slap on the wrist if the mods think it necessary; I'd rather slap her ass
